* This value corresponds to the switch/disconnect capacity, to the power distribution bus bar system capacity (if used) and to the protection circuit capacity in the
standard unit.
** If the available short-circuit current is higher, the unit can be protected by the fuse shown for the specific level.
The fuses (not supplied for Carrier units) are as recommended, to be installed upstream of the unit. A fused disconnect switch, equipped with fuses, can be installed
in place of the standard unit switch. This should be done on site; please contact the local service department or a qualified electrician. Alternatively please order the
special version from the factory by contacting your local Carrier dealer.

*** Shows the new protection values with higher-capacity fuses than those specified in the previous column. If such fuses are part of the electrical installation
upstream of the unit, this is sufficient as anti-short circuit protection to the specified level, without additional protection.
**** If a protection device, other than the recommended fuses above, is used for the installation to ensure that no additional protection is required, the protection device
must have the specified thermal limit (I
2
t) and limit effect characteristics for the short-circuit current. If the protection device does not have the specified
characteristics, one of the specified protection fuses from the previous columns must be installed.
b. 30RY 040-080 – outdoor installation
Environment** - Environment as classified in EN 60721 (corresponds to IEC
60721):
- outdoor installation**
- ambient temperature range: -10°C to +46°C, class 4K3**
- altitude: ≤ 2000 m
- presence of hard solids: class 4S2** (no significant dust present)
- presence of corrosive and polluting substances, class 4C2 (negligible)
- vibration and shock, class 4M2
Competence of personnel, class BA4** (trained personnel - IEC 60364)
2. Power supply frequency variation: ± 2 Hz.
3. The neutral (N) conductor must not be connected directly to the unit (if
necessary use a transformer).
4. Overcurrent protection of the power supply conductors is not provided with
the unit.
5. The factory-installed disconnect switch(es)/circuit breaker(s) is (are) of a
type suitable for power interruption in accordance with EN 60947.
6. The units are designed for connection to TN networks (IEC 60364). For IT
networks the earth connection must not be at the network earth. Provide a
local earth, consult competent local organisations to complete the electrical
installation.
NOTE: If particular aspects of an actual installation do not conform to the
conditions described above, or if there are other conditions which should
be considered, always contact your local Carrier representative.
* The protection level required to conform to this class is IP21B (according to
reference document IEC 60529). All 30RY 017-080 units are protected to
IP23C and fulfil this protection condition.
** The required protection level for this class is IP43BW (according to reference
document IEC 60529). All 30RY 040-080 units are protected to IP45CW and
fulfil this protection condition.
Electrical data notes for 30RY units:
• 30RY 017-080 units have a single power connection point.
• The control box includes the following standard features:
- Starter and motor protection devices for each compressor, fan, optional
pump
- Control devices
• Field connections:
All connections to the system and the electrical installations must be in full
accordance with all applicable codes.
• The Carrier 30RY 017-080 units are designed and built to ensure conformance
with local codes. The recommendations of European standard EN 60204-1
(machine safety - electrical machine components - part 1: general regulations
- corresponds to IEC 60204-1) are specifically taken into account when
designing the electrical equipment.
IMPORTANT:
• Generally the recommendations of IEC 60364 are accepted as compliance
with the requirements of the installation directives. Conformance with EN
60204-1 is the best means of ensuring compliance with the Machines
Directive § 1.5.1.
• Annex B of EN 60204-1 describes the electrical characteristics used for the
operation of the machines.
1. The operating environment for the 30RY units is specified below:
a. 30RY 017-080 – Indoor installation

- humidity range (non-condensing)*:
50% relative humidity at 40°C
90% relative humidity at 20°C
- altitude: ≤ 2000 m
- indoor installation*
- presence of water, class AD2* (possibility of water droplets)
- presence of hard solids, class AE2* (no significant dust present)
- presence of corrosive and polluting substances, class AF1 (negligible)
- vibration and shock, class AG2, AH2
